The check-engine light means the car's computer has stored a fault code. The code tells us where to look, not always what to replace.
Steady light
The car has found a fault but it isn't urgent. Drive gently and book a diagnosis soon.
Flashing light
This usually means a misfire that can damage the catalytic converter. Slow down, stop when it's safe, and call us.
What a diagnosis involves
We connect a scanner, read the stored codes, look at live sensor data, and then inspect the part the data points to. You get a list of what we found before any work starts.
